COURSE OBJECTIVES:
Students will acquire knowledge about the key introductory concepts of chemical bonding, acid-base chemistry, and properties of p- block elements as well as use this knowledge for qualitative and quantitative analysis of inorganic compounds during laboratory work.
COURSE OUTLINES:
Chemical Bonding:
Types of chemical bonding, ionic and covalent bonding, localized bond approach, theories of chemical bonding, valance bond theory (VBT), hybridization and resonance, prediction of molecular shapes using Valence Shell Electron Pair Repulsion (VSEPR) model, molecular orbital theory (MOT) applied to diatomic molecules, delocalized approach to bonding, bonding in electron deficient compounds,hydrogen bonding.
Acids and Bases:
Brief concepts of chemical equilibrium, acids and bases including soft and hard acids and bases (SHAB), relative strength of acids and bases, significance of pH, pKa, pKb and buffer solutions, theory of indicators, solubility, solubility product, common ion effect and their industrial applications.
p-Block Elements:
Physical and chemical properties of p-block elements with emphasis on some representative compounds, inter-halogens, pseudo-halogens and polyhalides.
PRACTICAL:
Lab safety and good laboratory practices, knowledge about material safety data sheets (MSD), disposal of chemical waste and first-aid practices, qualitative analysis of salt mixtures, quantitative analysis, acid- base titrations, preparation and standardization of acid and alkali solutions, redox titrations, preparation and standardization of potassium permanganate solution and its use for the determination of purity of commercial potassium oxalate or oxalic acid, preparation and standardization of sodium thiosulfate solution and its use in determination of copper in a given sample, gravimetric analysis, determination of barium in a given sample, determination of chloride in a given solution.
